Is collagen an inorganic molecule?

Like all proteins, collagen consists of amino acids, organic molecules made from carbon, hydrogen, and oxygen. Collagen actually is a family of proteins rather than one specific protein, plus it is a complex molecule, so you won’t see a simple chemical structure for it.

Is collagen an organic component?

Collagen is formed of amino acids; basic organic compounds made up primarily of Carbon, Oxygen, Hydrogen and Nitrogen, which are the constituent parts of most proteins. The amino acids are arranged in triple helical chains as shown below, which differ in length and size depending on the type of collagen.

What makes up the organic and inorganic portions of bone?

Organic part of bone is a protein Ossein and Collagen fibres. Inorganic part of bone is mainly Calcium Phosphate. The inorganic mineral is responsible for its hardness.

What is inorganic matrix of bone?

The inorganic matrix of bone consists of a calcium hydroxyapatite, which is in a crystalline structure. This serves to: 99% of the body’s calcium, 85% of its phosphorous, 65% of its sodium and magnesium.

Is collagen a secondary or tertiary structure?

Collagen is a protein. All proteins have a tertiary structure. Only some proteins have the quaternary structure.

What type of macromolecule is collagen?

protein
Collagen is the most abundant mammalian protein. It is the main component of skin, bones, and teeth. This protein is composed of three helical polypeptide chains that form a stiff, supercoiled cable. The type of helix in each polypeptide is unique to collagen and results from collagen’s unusual amino acid composition.

What type of collagen is in cartilage?

type II collagen
Articular cartilage contains at least five genetically distinct types of collagen. Types II, IX, and XI are cartilage-specific and are cross-linked together in a copolymeric network that forms the extracellular framework of the tissue. Fibrils of type II collagen provide the basic architecture.

What percent of bone is collagen?

90%
Approximately 60% the weight of the bone is mineral, mainly calcium and phosphate. The rest is water and matrix, which is formed before the mineral is deposited, and can be considered the scaffolding for the bone. About 90% of the matrix proteins are collagen, which is the most abundant protein in the body.

Are bones made of organic or inorganic?

Bone is a composite material consisting of both inorganic and organic components [1,2,12]. The inorganic component is primarily crystalline hydroxyapatite: [Ca3(PO4)2]3Ca(OH)2. The organic component of bone comprises more than 30 proteins with type I collagen being the most abundant (>90%) [1,2,12].

What is an organic matrix?

When the inorganic portion of a bone is dissolved with acid, there remains a model of the bone in a coherent elastic material that is sometimes referred to as the organic matrix. The term matrix, which is widely used in descriptive anatomy, is derived from a Latin word meaning womb or uterus.

Are glycoproteins organic or inorganic?

The organic matrix of bone contains several protein families, including collagens, proteoglycans, and glycoproteins, all of which may be extensively modified by posttranslational events, such as phosphorylation and sulfation.

Is collagen hydrophilic or hydrophobic?

Collagen is a largely hydrophobic molecule (water repelling), whilst sugar molecules generally have a hydrophobic and a hydrophilic face.

Is NaNO3 organic or inorganic?

nitrate (NO3) Inorganic or organic ester or salt of nitric acid , containing the (NO3-) ion. Nitrates are the most water soluble of all salts, and play a major part in nitrogen cycle and nitrate pollution. Inorganic nitrates are formed by bacteria and are an essential component of agricultural soil.

Is monosodium glutamate organic or inorganic?

Monosodium glutamate (mon-oh-SOH-dee-yum GLOO-tuh-mate) is an almost completely odorless white crystalline powder. It is the sodium salt of a common amino acid called glutamic acid. An organic salt is a compound formed when an inorganic base, such as sodium hydroxide, reacts with an organic acid, such as glutamic acid .

Is starch oganic or inorganic?

Starch, a white, granular, organic chemical that is produced by all green plants. The basic chemical formula of the starch molecule is (C6H10O5)n. Starch is a polysaccharide comprising glucose monomers joined in α 1,4 linkages. The simplest form of starch is the linear polymer amylose; amylopectin is the branched form.

Is urea an organic compound or inorganic?

Urea is a white crystalline substance with the chemical formula CO(NH2)2; it is highly water soluble and contains 46% nitrogen. Urea is considered an organic compound because it contains carbon. It was the first organic compound ever synthesized by chemists; this was accomplished in the early 1800s.
