I have a question asking about 2 uses of triglycerides. I only know about its use as a storage molecule of energy. Unless it being a component of fat counts as a separate point, I don’t know what else the use could be. If anyone could give me a hand, I’d be grateful

Like you said: triglycerides are used as an energy store. But ensure that you understand why it's good for these uses as well. They are a good energy store because when oxidised, they provide twice the energy as the same mass of carbohydrates.
Triglycerides are also stored around vital organs for their protection.
They are also a thermal insulator. Since fats are slow conductors of heat, when stored beneath the body surface they help to retain body heat.

Thanks a lot - that’s fantastically useful

Couple of extra points for you (in case you get a similar type of synoptic Q (to aim for A*):-

1. As ambassador [binomial series] says, fats give approx. twice the number of calories per unit mass - to be exact, fats give 9.1 Kcal/g, carbohydrates 4.1 Kcal/g and proteins 4.1 Kcal/g (you can convert these figures into joules/g by multiplying by 4.2).
2. Fats also have an additional function, namely in reproduction i.e. perpetuation of the species: fat deposition in the breasts and around the hips of women give them the "hour-glass" shape that men find attractive (at least some men like I do: I suppose evolution has now made men prefer girls who are skinny - I am stumped to work out the adaptive advantage of this modern trend! - the traditional attractiveness of a woman was so, in evolutionary terms, because a rounded bottom makes a woman more capable of giving birth).
