Question

Describe how the protein "titin" is used in cotton fibres? give a solid example

Answer 1

Titin is a connectin, a protein that, in humans, is encoded by TTN gene. This is a giant protein, greater than 1um in length. It is composed of 244 individually folded protein domains connected by unstructured peptide sequences. These domains unold when the protein is stretched and refold when tension is removed. Titin is important in the contraction of striated muscle tissue. It is the third most abundant protein in muscle. This is mostly present in muscle tissue and has only function in humans.

Cotton is made of carbohydrate called cellulose. Cellulose is a polymer made up of glucose. Cotton fibres are made more or less the dried-out remains o extraordinarily long and thick cell walls. Cotton is a soft, fluffy staple fiber that grows in a boll, r protective case, around the seeds of the cotton plants f the genus Gossypium. The fibre is almost pure cellulose.

So titin protein cannot be used in cotton fibres.
