Globular and fibrous protein a level
WebJan 9, 2024 · There are two main classes of 3D protein structure: globular proteins and fibrous proteins. Globular Proteins. Globular proteins are usually round and ball-shaped. They usually have metabolic functions, for example, they may be enzymes or antibodies. Haemoglobin is an example of a globular protein. Fibrous Proteins. … WebThe major distinction between fibrous and globular proteins is that fibrous proteins are composed of long, narrow strands, whereas globular proteins are compact and …

WebA. Fibrous proteins In these protein, the molecule are constituted by several coiled cross-linked polypeptide chains, they are insoluble in water and highly resistant to enzyme … WebGlobular proteins are compact, roughly spherical (circular) in shape and soluble in water. Globular proteins form a spherical shape when folding into their tertiary structure because: their non-polar hydrophobic R groups are orientated towards the centre of the protein …
WebGood overall response to the question. The answer is rather short but provides a perfect example of what an A level candidate should be aiming for in terms of length and segregation of the different parts, going for comparison rather than describing each protein separately which is good in this instance. The response to the question is clear and concise. WebGlobular Proteins. Molecule forms a coiled shape (globule) Hydrophobic groups point into centre of molecule away from water; Only hydrophilic groups are exposed outside the …
